LHC can't cause a black hole as it does not generate enough energy.
This is a statement made by people who did not know what LHC was and was it was going to be used for. In worst case the swiss will be blown away, but forget black hole creation.
Should mini black holes be created in high-energy particle collisions, they would evaporate very fast, due to Hawking radiation.
So forget the theory of black holes eating up the earth
